Abstract

PURPOSE:To shorten the time necessary for the development of a side air bag up to a prescribed position such as the side of a driver's head part by tentatively fitting a vertical development part in folded state to be expandable upward to a horizontal development part and releasing the tentative fitting when the horizontal development part is expanded by a prescribed quantity, and developing the air bag upward from the vertical development part. CONSTITUTION:As for an air bag having a vertical development part V which is communicatively-formed in airtight form in the upper part of a horizontal development part H, the vertical development part V is tentatively fitted in folded state in the horizontal development part H, and further the horizontal development part is folded and accommodated in a side door 11. When the nitrogen gas, etc., which are generated when collision is detected is supplied into an air bag 17, firstly the horizontal development part H expands nearly horizontally in the car room inside direction, and is developed on the side of a driver's chest part. In this case, the vertical development part V is tentatively fitted as in its folded state to the horizontal development part H, and development is regulated. When the horizontal development part H expands by a prescribed quantity, the tentative fitting of the vertical development part H is released by the rise of the gas pressure in the horizontal development part H, and the vertical development part V expands upward.

When a collision sensor (not shown) installed in 1 or the like detects a side collision and outputs an ignition signal, the inflator 16 is ignited and nitrogen gas is generated.
First, the horizontally expanded portion H of the airbag 17 is inflated substantially horizontally toward the passenger compartment (see FIG. 2). Expanding horizontal expansion part H
When the internal pressure of the cylinder rises above a certain level, the vertical expansion part V
The temporary fastening yarn 18 that holds the folded state of No. 1 and is temporarily fastened to the horizontal unfolding portion H and that restricts further expansion of the horizontal unfolding portion H is broken (see FIG. 3). Therefore, after the horizontal deploying portion H is sufficiently inflated and deployed to the side of the occupant's chest, the vertical deploying portion V regulated by the temporary fastening yarn 18 is allowed to expand. Therefore, the vertical expansion portion V expands vertically upward. At this time, the vertical deployment portion V is deployed to the side of the occupant's head by the tether 17a stretched between the opposing inner surfaces so that the thickness when inflated becomes constant,
Ensure occupant protection from secondary collisions (see Figure 4).
